vided with a coin slot 5. .As shown In Fig. 2 a vertical partition 6 is arranged in the box -1 near the left hand wall thereof and supported on the partition 6 is a coin chute having three legs 7, 8 and 9. The coin chute has flanges 10 and the upper chute, as shown in Fig. 2, is slanted laterally, and the space between its flanges 10 is such that if a coin, which is smaller than the required size, is inserted through the slot 5, it will roll but a short way down the upper leg 7 and will be tipped out sidewise by the slant of the upper leg 7 and fallout of the chute and drop to the bottom without operating any of the parts.

A coin of the required size and weight will roll to the bottom of the coin chute and drop the end'of alever 12 which is pivoted at 13, and will raise a hook 14 on. the lever 12 out of engagement with a shoulder 15 formed on a plate 16 fixed-on a shaft 17. A curved guard 1S1which lies back of the pocket 11 willretain'the coin in the pocket 11 to hold turned to o eratethe machine. As the shaft ,17 is turne'" the plate 16 is rocked therewith which bears against the curved edge of the plate 16 until the plate is turned far enough to allow the finger 19 to drop into a recess 20 in late 16, whereupon the weight of the coin epresses the lever 12 slightly farther a sufficient amount to allow'the coin to roll out of the pocket 11 under the lower edge of the guard 18. The outer end of shaft 17 is provided with an operating handle 21 as shown in Figs. 1 and 2, but the shaft 17 cannot be rocked forward until the shoulder 15 ofplate 16 is freed by the hook 14 of lever 12, and the lever when weighted by the coin, is held free from the plate as described until the plate has been turned. The lever 12 is suitably counterbalanced by a weight 22 on the forward end thereof.

A flat spring 23 having a bowed upper end, as shown in Fig. 2, is secured to the partition 6 and at an intermediatepoint a pin 24 projects inward from the sprin 23. he lower end of spring 23 is provide with a shoe 25 which normally rests against the flat face of the plate 16 thus holding the spring 23 in the position shown in full lines in Fig. 2. When, however, the shaft 17 has been rocked for-' ward to operate the machine and the plate 16 has been moved into the position shown in Fig. 4, the shoe 25 is freed from the plate into a coin pocket 11 which is arranged on the lever 12 tipped while the shaft .17 is being" and the lever 12 is srstained bv a-fing'erll 16 and the spring 23 bendsinward into the chine, t at coin will be arrested in its downward travel by the pin 24 and will be held there until the parts have been restored to normal position, at which time the spring 23 is again sprung back b plate 16 and withdraws the in 24 and t e coin will then roll down and rop into the pocket 11" and oper-. ate the lever 12. As at this time the ma chine is again in normal condition, and the coin has tipped up the lever, the customer may operate the machine and get his paper. This prevents a customer from losing his coin without receiving a pa er if he should drop the coin in at a time w en the machine was not in normal condition.

Fixed to the shaft 17 is a pair of arms 26 and 27 as shown in Fig. 2, and the arm 26 is provided with an abutment 28, clearly seen in Figs. 5 and 6, which is adapted to act upon a foot 29 to depress an operatin rod 30 every time the handle 21 is operate forward to work the machine. The operating rod 30, as shown in Fi 9, is slidable vertlcally in brackets 31 whichare screwed to the inside and prevent the insertion of a coin.-

of the front cover 2. A coil tached to the upperend of r0 5 30 for draw ing it up. A'spring pawl 33 is attached to rod 31 and operates a dial 34 having ratchet teeth. A spring retaining pawl 35 isprovided for reventing reverse movement of the dial. l astened to the dial 34 is a shutter 36 which, when the dial 34 has been turned far enough, will stand back of the coin sloti15 e dial34 is rovided with numerals, and an indieatin gel 37 is fastened to the'cover 2. The dia 34 is operated one ste for each operation of the machine and t e handle 21 must be operated the full stroke in order to bring the shoe 28 against the foot 29 to operate therod 30 and this prevents the dial being turned unless the machine is given a complete operation The dial 34 may be manually set so that after the certain number of papers with which the machine has been sup lied have been vended, the

shutter 36 wil have progressed intoya osition shutting the slot 5, the dial 34 ma ring one step for each paper vended. in filling the machine with the papers it is a simple matter to set the dial so that the numeral on the dial whichcorresponds to the numing32 is at.

pivoted at 41 andhas a spring 42 connecte to a centrally located ug 43,.such

that the pawl 40 is operative to check repawl will permit this forward movement but will prevent reverse movement until after the plate 38 has been moved forward sufiicient to clear the plate 38 as shown in Fig. 6. Then in movin the plate 38 back, the awl acts against t e otherside of the teetli 39 and reve'nts reverse movement of plate 38 unti it has been completely restored, it being necessary whenthe plate has been partially moved along the pawl, to complete the movement and brin the late entirely out of engagement with t e pawl to permit the plate to be turned back, and vice versa.

A horizontal shelf 44is provided, as shown in Fig. 2, and the pa ers 45 which are to be vended are arranged in pack form on the shelf'44 as shown in Fi 5. The papers are introduced in position from the front of the machine and the pack is automatically pressed rearward by a follower 46 which con sists of a flat plate-preferably having a knob 47 by which it may be removed when freed. The follower 46 if constructed of wood is referably provided with four metal face-p ates 48. A follower frame 49 is hinged at 50 to the shelf 44 to swing outwardly. The fol, lower frame 49 is a rectangular frame and has a horizontal central bar 51 as clearly shown in Fig. 2. A'pair of fingers 52 are hinged at 53 tothe upper edge of the bar 51- and, as shown in Figs. 5 and 6, each finger 52 has' a short arm 54 with which coil springs 55 are connected which serve to yieldingly hold the fingers 52 against the two lower face plates 48. A similar pair of fingers 52 and associated devices are extended above thebar 51 and bear against thetwo upper face plates 48; The arms 54 are comparatively short and'thus partake of a relatively small amount of movement compared to that of the free ends of the arms 52. This construction allows a wide range of movement of the follower 46 and the arms 52 yieldingly press the follower 46 rearwardly and the pack of pappm with it as fast as the pa ers are vended.

he follower frame 51 is hel in normal position by a pair of buttons 56 which engage the upper edge of the frame, as shown in Fig.2. By releasing the buttons 56, the follower frame 51. and parts carried by it may be swung back bodil lines in Fig. 5. T e front cover, of course, must be opened to give access to the interior before this can be done. in this view the follower frame is shown as having been swung only part way back, it being possible to swing the follower frame to a horizontal as indicated in dotted position and even lower which obviously gives perfect access to the follower 46 to remove or replace the. same and permits the slide. The drawer 58 comprises a rectangu-- lar frame 59 having near its front a thin plate 66 formed ireferably of aluminum, see Figs. 5 and 6. his plate 60 is permitted to yield slightly in the frame 59 and has lugs 61 which slidahly fit in grooves 62 formed in the wall of the box 1 and artition 6. The purpose of this is to enab e the drawer to be adjusted to vend papers of different thicknesses, as will be more fully described. The lower part of the drawer 58 is connected to a rectangular block 63, and projecting forward from the block 63 is a pair of slotted brackets 64 as shown in Figs. 2 and 5, and the arms 27, before referred to, are provided with studs 65 which engage in the respective slotted brackets 64 so that as the shaft 17 is rocked, the drawer 58 is moved vertically.

The upper edge of the block 63, that is, that slight portion of its edge which is forward of the plate 60, acts as an abutment which lifts against the lower edge of the paper to be lifted and vended. This is clearly seen in Figs. 5 and 6. In Fig. 5 the block 63 is shown in normal position, and the rear most paper 45 is resting with its lower edge upon the upper edge of theblock 63, and the p ate 66 is flatly supporting the rearmost paper 45 of the pack. The plate 60 is adjustably held against the paper by a pair of arms 66, see Figs. 5, 6, 7 and 8, the lower ends of arms 66 being hinged at 67 to a stationary thin horizontal bar 68 which extends across the box. The up or end of each arm 66 is provided with a ro ler 69 which bears against the plate 60. A shaft 70 extends across the machine and is provided with a pair of cams 7 1 which bear against the respective arms 66. By turning the shaft 70 the cams 71 are ad- {usted to move the fingers 66 forward or alow the fingers to retract according to the space required in front of the plate 60 as determined by the thickness of the paper being venderh These rollers reduce friction during the sliding movement of the plate, and their adjustment determines the space between the plate and front wall of the slot through which the drawer slides. It will be seen that the plate is not rigid but is free to rock slightly on the rollers to adjust itself flatly to the paper. An arm 72 is attached to one end of shaft 76 and is detachably held in place by a notched dial 73, arranged on the inside of the left end of the box, see Fig. 10 and Figs. 7 and 8. The dial 73 serves to indicate the the paper 45.

position in which to set the arm 72 for certain thicknesses of papers.

A pair of s ring arms 74 are fastened to the back of the rawer 58, and each arm 74 at its upper end has a forwardly projecting pin 75 which is adapted to be rojected through a registering hole in the p ate 60, as shown in Fig. 6, to press forward the upper edge of This action is accomplished automatically by means of shoes 76 which are arranged on the back of the respective arms 74 and which ride over brackets 77 at the upper wall of the box 1, the brackets 77 being stationary and causing the shoes 76 to press the arms 74 forward as the drawer is slid up, this action taking place only durin a short upward movement of the drawer as t is shoes 76 ride over the short brackets 77. As the arms 74 are thus automatically moved forward, the pins 76 are thrust against the edge of the paper 45, bending the paper forward into a position such that it may be easily gras ed by the hand and withdrawn from the mac ine. A pair of rock arms 78 are pivoted in the upper wall of the box and pro'ect above the same and are connected by a ail 79. A coil spring 80 is arranged in front of each rock arm and serves to press it rearwardly. The-drawer 58 on each side has a pair of notches 81 and 82 and each rock arm ias upper and lower detents 83 and 84.

When the drawer is pushed up to vending position as shown in Figs. 1, 4, 6, and 12-, the detents 83 engage in the notches 81 and sustain the drawer. As the customer pulls out the paper it is necessarily drawn somewhat forward over the bail 79 and moves the bail forward which draws the detents 83 out of the notches 81 and moves the detents 84 against the smooth face of the drawer frame slightly below the notches 82, this position of the parts being shown in Fig. 13; the drawer having thus been released by detents 83, drops slightly until the notches 82 come opposite detents 84 whereupon the latter are moved into notches 84 and the detents 83 are above the line of notches 81, as shown in Fig. 14. The drawer is thus held up until the paper has been completely withdrawn whereupon, pressure of the paper against bail 79 being removed, the springs 80 rock the detents 84 out of notches 82 and move the detents 83 against the smooth face of the drawer above the notches 81 and the drawer being thus released falls down and resumes its normal closed position. This double acting catch thus automatically latches the drawer while open and holds the door up while the pa er is being withdrawn, and automatically un atches the drawer and allows it to fall after the paper has been withdrawn. After the paper has been withdrawn, the follower plate moves the pack of papers back against the plate 60 and the drawer drops and the parts return to normal position. It is obviously All.

necessary that the drawer and all parts be restored to normal position before another paper will be vended, and if another coin should be inserted while the drawer was open, the coin will not act until the parts are returned to normal position, as heretofore ex laine l.
